Answer: c) 75
There are 75 possible arrangements exist.
Step-by-step explanation:
Given : The number of choices for Colors = 5
The number of choices for Sizes = 5
The number of choices for Extras = 3
WE assume that all skates are sold with ONE extra .
Then by Fundamental counting principle , the total number of different possible arrangements exist = ( number of choices for Colors ) x (number of choices for Sizes) x (number of choices for Extras )
= 5 x 5 x 3 = 75
Hence , there are 75 possible arrangements exist.
Thus , the correct answer is c) 75 .
